Heart Murmurs and Heart Sounds: Visual Explanation for Students

In this video I help you understand heart murmurs and heart sound using a simple explanation with illustrations and animations. We cover the heart sounds S1, S2, S3 and S4, mitral stenosis, mitral regurgitation, aortic stenosis and aortic regurgitation. We also discuss the features of murmurs, grades of murmurs and how dilatation and hypertrophy are linked to valve pathology.
Special thanks to www.thinklabs.com for allowing me to use with permission the heart sounds recorded on a Thinklabs Digital Stethoscope and available at:

As a newly qualified paramedic this video is amazing! We brushed over heart sounds at uni as told they were a "nice to know" rather than a need to know. This has really helped me get my head around what normal should sound like and what abnormal actually means. Thank you so much!!

[@markgrenier6787]

As an intensive care nurse I'm constantly checking the heart and lungs and I found this information very helpful I'm going to listen to it over and over again until I have it nailed down but thank you for taking the time to enlighten me you've made a sacrifice for me and I am going to be forever thankful and my patients will get better

Best video on murmurs I have found so far.

[@nikiluvsyou]

I grasp more of the information from watching your video than i did watching others, because you didn't rush through the explanation, so it gave me time to process the information in my head. I also appreciate that you replayed the sounds a second time.

Amazing video! Thanks. I got to listen to the murmurs, and I found that really interesting. Hopefully, when I get back on the ward, I would practice more until I am able to effortlessly identify each murmur.

[@sagarjigar]

Dude, you are awesome! Just love the way you explain things into small bits and then explain in such a simplistic manner.

Being born with a bicuspid aortic valve and at 50 yrs old replaced with a bovine valve this was very informative. 👍

I want to salute you for making me understand murmurs that too with actual haemodynamics. You are amazing. Sir. My regards.

[@carapurdy9520]

Thank you for including ehlers-danlos syndrome and Marfan's syndrome - more people need to be aware of these diseases.

I'm a nursing student working with asthma patients at present, so naturally I've bought myself a stethoscope... the first thing hubby said to me was 'now you'll be able to hear my heart murmur!' I had no idea there was more than one! Tomorrow morning we'll see if I can recall all this and find out WHICH one! I'll let you know!

[@BIGVISIONINDIAN]

[@hamnaurooj2225]

Amazing video. A tip is you might wanna decrease the speed to 0.25 or 0.5 x in order to be able to listen to the heart sound clearly and try to appreciate the murmur. Once you’re good then hear it on normal speed.

[@user-wu5hl4dh8z]

It really helped me, thanks. But i couldn't separate the second and third sound even using this lifehack

[@chintanmistry7129]

Your explanation is very calm, short and very easy to remember, along with animation that explains the pathology quite easily. Thank you.
